2026-03-09docs: filesystems: clarify KernelPageSize vs. MMUPageSize in smapsDavid Hildenbrand (Arm)
There was recently some confusion around THPs and the interaction with KernelPageSize / MMUPageSize. Historically, these entries always correspond to the smallest size we could encounter, not any current usage of transparent huge pages or larger sizes used by the MMU. Ever since we added THP support many, many years ago, these entries would keep reporting the smallest (fallback) granularity in a VMA. For this reason, they default to PAGE_SIZE for all VMAs except for VMAs where we have the guarantee that the system and the MMU will always use larger page sizes. hugetlb, for example, exposes a custom vm_ops->pagesize callback to handle that. Similarly, dax/device exposes a custom vm_ops->pagesize callback and provides similar guarantees. Let's clarify the historical meaning of KernelPageSize / MMUPageSize, and point at "AnonHugePages", "ShmemPmdMapped" and "FilePmdMapped" regarding PMD entries. While at it, document "FilePmdMapped", clarify what the "AnonHugePages" and "ShmemPmdMapped" entries really mean, and make it clear that there are no other entries for other THP/folio sizes or mappings. Also drop the duplicate "KernelPageSize" and "MMUPageSize" entries in the example.

2026-03-09dt-bindings: fsl: imx7ulp-smc1: Add #clock-cells propertyPeng Fan
The SMC1 block on i.MX7ULP is already used as a clock provider in imx7ulp.dtsi, but the corresponding dt-binding schema does not define the required '#clock-cells' property. This results in CHECK_DTBS schema validation errors. Functionally, SMC1 controls the CPU run mode configuration: - 00b: Normal Run (RUN) - 10b: Very-Low-Power Run (VLPR) - 11b: High-Speed Run (HSRUN) These run modes determine the effective CPU operating point, and their programming is tied to the OPP table. Add the missing `#clock-cells` definition so the dt-binding schema is consistent with the DTS and validates correctly.

There are several devices supporting a choice of eMMC or SD on a single board by both dip switch and gpio, e.g. Renesas RZ/G2L SMARC SoM and SolidRun RZ/G2L SoM. In-tree dts for the Renesas boards currently rely on preprocessor macros and gpio hogs to describe the respective cards. By adding mux-states property to sdhi controller description, boards can correctly describe the mux that already exists in hardware - and drivers can coordinate between mux selection and probing for cards.

Document new property arm,no-completion-irq . This optional property is intended for hardware that does not generate completion interrupts and can be used to unconditionally enable forced polling mode of operation. With this property set, such implementations which do not generate interrupts can be interacted with, until they are fixed to generate interrupts properly. Note that, because the original base protocol exchange also requires some sort of completion mechanism, it is not possible to query SCMI itself for this property and it must be described in DT. While this does look a bit like policy, the SCMI provider is part of the hardware, hence DT.

2026-03-07scsi: ufs: core: Add support to notify userspace of UniPro QoS eventsCan Guo
The UniPro stack manages to repair many potential Link problems without the need to notify the Application Layer. Repair mechanisms of the stack include L2 re-transmission and successful handling of PA_INIT.req. Nevertheless, any successful repair sequence requires Link bandwidth that is no longer vailable for the Application. Therefore, it may be useful for an Application to understand how often such repair attempts are made. The DME implements Quality of Service monitoring using a simple counting scheme, counting error events and comparing them against the number of correctly received or transmitted bytes. When the error counter exceeds a programmed threshold before the byte counter overflows, a DME_QoS.ind is issued to the Application and both counters are reset. When the byte counter overflows before the error counter has reached the programmed threshold, both counters are reset without triggering a DME_QoS.ind. The DME provides Link quality monitoring for the following purposes: 1. Detection of re-occurring repaired fatal error conditions on the Link (PA_INIT loop). This kind of detection is useful if capabilities exchanged between local and peer permit a potential operation at a higher M-PHY Gear, but the physical interconnect between local and peer Device does not, or, after Line quality degradation, no longer satisfies channel characteristics. 2. Detection of degraded inbound or outbound Link quality, to allow an Application to issue an ADAPT sequence for a Link running in HS-G4 or higher HS Gears. This kind of detection is used to monitor a slowly degrading Link quality, e.g., one being affected by temperature and voltage variations, against the expected M-PHY bit error rate. Userspace can configure and enable UniPro QoS via UniPro QoS Attributes (via UFS BSG) and get notified by dme_qos_notification without polling UniPro QoS Status attribute. The dme_qos_notification attribute is a bitfield with the following bit assignments: Bit Description === ====================================== 0 DME QoS Monitor has been reset by host 1 QoS from TX is detected 2 QoS from RX is detected 3 QoS from PA_INIT is detected Signed-off-by: Can Guo <can.guo@oss.qualcomm.com> Reviewed-by: Bart Van Assche <bvanassche@acm.org> Reviewed-by: Peter Wang <peter.wang@mediatek.com> Link: https://patch.msgid.link/20260305110856.959211-2-can.guo@oss.qualcomm.com Signed-off-by: Martin K.

This series enables QoS configuration for QNOC type device which can be found on QCS8300 platform. It enables QoS configuration for master ports with predefined priority and urgency forwarding. This helps in prioritizing the traffic originating from different interconnect masters at NOC (Network On Chip). The system may function normally without this feature. However, enabling QoS helps optimize latency and bandwidth across subsystems like CPU, GPU, and multimedia engines, which becomes important in high-throughput scenarios. This is a feature aimed at performance enhancement to improve system performance under concurrent workloads. * icc-qcs8300 dt-bindings: interconnect: qcom,qcs8300-rpmh: add clocks property to enable QoS interconnect: qcom: qcs8300: enable QoS configuration Link: https://msgid.link/20260127090116.1438780-1-odelu.kukatla@oss.qualcomm.com Signed-off-by: Georgi Djakov <djakov@kernel.org>
